Peptide Reconstitution Setup Guide

Enter 250mcg which is the same as 0.25mg as your target amount per aliquot. You want each measured aliquot to contain 250mcg of peptide, so you specify this amount.

Enter 5mg in the calculator, since it says 5mg on the vial.

You decided to dilute your peptide with 3mL of Bacteriostatic water so enter 3mL. (Consult Bac Water Calculator to determine this amount.)

The visual meter will show that you need to draw up 15 units on your syringe to measure out 250 mcg. Since 1mL equals 100 units on the syringe, 0.15mL equals 15 units.

Example: Calculating Your Aliquot Volume

In this example we will assume your peptide strength is 5mg, and you will add 3mL of bacteriostatic water. Your goal is to measure out 250 mcg of peptide in solution.

1
Set Your Target Amount
Enter 250mcg (0.25mg) as your target amount per aliquot.
2
Enter Peptide Strength
Enter 5mg in the calculator, since it says 5mg on the vial.
3
Add Water Volume
Dilute your peptide with 3mL of bacteriostatic water so enter 3mL.
4
What the Calculator Does
The calculator determines concentration: 5mg (5000 mcg) dissolved in 3mL of water. It then works out how much to draw up to measure 250 mcg — 0.15mL, or 15 units.
5
Check the Visual Volume Meter
The visual meter confirms 15 units on your syringe measures 250 mcg. 1mL = 100 units, so 0.15mL = 15 units.

Summary

Mixing 5mg of peptide with 3mL of bacteriostatic water creates a solution with a concentration of ~1.67 mg/mL. To measure out 250mcg, draw up 0.15mL (or 15 units) of this solution.
